I have been trying to install lablgtk2 on my wodi32 cygwin since the package environment did not initially come with lablgtk (just lablgtk).
I followed these directions to do it manually myself:
2) Install lablgtk2 binaries and scripts inside the OCaml distribution
bin/* -> bin
lib/site-lib/lablgtk2 -> lib/site-lib/lablgtk2
Then edit lib/ld.conf, and add the line
\lib\site-lib\lablgtk2
3) If your distribution is newer than 4.00.0, go to the
lib/site-lib/lablgtk2 directory and execute
ocaml build.ml
But it doesn't seem to be working right. Is there a Wodi method of doing this?
